LEWIS DEMOTT BUNCE, OF SALT LAKE CITY, UTAH TERRITORY.

CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 369,583, dated September 6, 1887.

7 Application filed February 10, 1887. Serial No. 227,194. (N omodel.)

To all whom it may concern.-

Be it know n th at I, LEwIs DEMOTT Boson, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and useful Improvement in Ohurn-Dashers, of which the following is a specification.

My invention is an improvement in churndashers; and it consists in certain constructions and combination of parts forming the churndasher, as will be hereinafter described.

In the drawings, Figure 1 is a side elevaiion, part in section, of my improvement. Fig. 2 is a top plan view thereof. Fig. 3 is an enlarged detached section of the lower part of the dasher, showing the shaft in full lines. Fig. at is a detail perspective view of the dash er-shaft, partly broken away, and showing the pinion and the winged portion of the shaft.

The churn-body A may be of any desired form or material, and may be provided with the internal breakers, a, and with the legs B. These legsB are formed of round rods of metal bent upon themselves, and having their ends flattened at b and arranged to be secured to the outer side of and the bottom of the body or tub A, as will be understood from Fig. 1. These form light and economical legs, which may be readily removed to save space in storage and transportation.

The cover 0 is rabbeted, to properly fit the mouth of the body or tub A. This cover 0 forms only a part of the churntop, the lid H completing the top and being easily removable, so access may be had to the contents of the tub or body.

On the cover 0, I secure a base-plate, I, made of a sufficient width to cover a considerable portion of the surface of the cover, to

warping. On the inner end of this plate I form an arch-bracket, J, having a horizontal bearing, j, for the shaft K, and provided in the under side of its crown with a bearing, 1, for the upper end of the vertical dasher-shaf t L, which latter is stepped at its lower end in a bearing, L. At its outer edge the plate I has a bracket 1, having a bearing, t", for the outer end of shaft K, which latter has acrank-handle, k, by which it may be turned. On the shaft K, I support a bevel gear-wheel, M, having a hub, m, through which a clamp-screw is turned and engages shaft K, so that the wheel M may be secured in any desired adjustment. This gear meshes a pinion, N, fixed 011 shaft L, the said pinion being provided at its lower edge with a cuplike receptacle, n, to catch the lubricating-oil and prevent the same from passing into the churn-body.

On the shaft L, near its lower end, I secure the dasher-blades O by means of the radial wings P, formed on and projecting from said shaft. These wings are formed by swaging out the shaft at a point short of its lower end to form the wings I, and by the formation of the wings I decrease the diameter of the shaft at the point where the wings are formed in a direction at right angles to the direction of said wings, thereby forming practically shoulders at p p to prevent any longitudinal play of the dashers on the shaft. In practice the blades have openings formed through them of such size as to properly receive the lower end of the shaft. Then as the shaft is driven therein its wings will open for themselves ways in the blades, and thereby prevent any turning of the blades on the shaft. As the wings force into the blades they force the fibers of the wood against the reduced portion of the shaft and between the shoulders 12 in such manner as to prevent any play of the blades longitudinally on the shaft. These wings may be formed on the shaft at a very small cost and form asimple and efficient means of securing the blades thereto.

A bung-hole is formed through the side of the body, near its bottom, to receive a bung, and by removing the latter the milk may be discharged.

Having thus fully described my invention,

what I claim as new, and desire Letters Patent, is

The combination, substantially as hereinbefore described, of the shaft having radial wings P, extended in the direction ofits length, the diameter of that portion of the shaft on which the wings are formed being decreased on a line at right angles to the line of projecto secure by tion of the wings, whereby shoulders 19 p are shoulders 19 1), whereby to prevent the blade provided, and the wooden blade or blades havor blades from moving longitudinally on the lug openings for said shaft, whereby when the shaft, substantially as set forth.

shaft is forced into the opening of the blade LElVIS DEMOTT BUNOE. 5 or blades the displacement of portions of the WVitnesses:
